SEL-3021-1 Serial Encrypting Transceiver

SEL-3021 Serial Encrypting Transceivers protect serial links for SCADA, Control, Maintenance, and other critical applications. FIPS 140 certified cryptographic product uses 128-bit AES Encryption to lock out cyber intruders & hackers.

  • Solve demanding serial encryption security applications with faster data throughput
    115,200 bits per second data rate.

  • Secure Protection of Serial Communications
    Use 128-bit Advanced Encryption Standard (AES) and session authentication to protect point-to-point or multidrop serial data links from attacks.

  • Easy Installation
    Use surface or DIN rail mounting and options to power from ac, station dc, or low-level dc sources.

  • Secure, Nonintrusive Setting and Monitoring
    Set and monitor through encrypted, authenticated wireless Ethernet link or wired USB 2.0 link and PC software.

  • Designed to satisfy dial-up security requirements set by NERC CIP Standards

  • Install an SEL-3021-1 at each remote terminal unit and master port. The SEL-3021-1 is optimal for both point-to-point and multidrop SCADA links. It includes support for multidrop protocols, with low latency for time-sensitive requirements.

  • Install an SEL-3021-1 on each maintenance port or port switch connected to maintenance ports. Set an SEL-3021-1 to match the encryption settings of the maintenance ports for each authorized engineer or technician. Prevent tampering with device settings and configurations.

  • Encrypt EIA-232 serial links that transfer private information, such as financial transactions, medical data, company trade secrets, commercial information, key customer information, routes, and schedules.
